What Really is Functional Training?

What Really is Functional Training?

• Function is purpose. When we ask what an items “function” is , we want to know it’s purpose.

• Think of functional training as purposeful training.

• Functional training is literally training muscles based on their function!

• From a scientific perspective it is “the application of functional anatomy to training”

Movements, Not Muscle Groups

Movements, Not Muscle Groups

• Forget bodypart divisions- chest and back etc.

• Learn basic anatomy• Learn true functional anatomy, it will change the way you think.

The BasicsThe Basics• Ligament- bone to bone, noncontractile, slow to heal, slow to adapt,

• Ligaments provide joint stability and proprioceptive input ( where the joint is in space)

• Made up of varying degrees of collagen ( tensile strength) and elastin (flexibility and recoil)

• Innervated by nervous system

MusclesMuscles

• Think of muscles as elastics or springs that connect bone to bone

• Muscles move or stabilize bones• Unlike ligaments muscles have the ability to lengthen and shorten

• Tendon connects muscle to bone• Tendons are the anchors for contraction and also have poor blood supply and heal slowly

Time Under TensionTime Under Tension• The length of a set =TUT• Set is a group of repetitions• A rep is expressed by tempo• Tempo is described by three numbers

• - Eccentric ( lengthen)• - Pause ( isometric)• - Concentric ( shorten)• Time under tension is the time it takes to complete a set

• The length of a set =TUT• Set is a group of repetitions• A rep is expressed by tempo• Tempo is described by three numbers

• - Eccentric ( lengthen)• - Pause ( isometric)• - Concentric ( shorten)• Time under tension is the time it takes to complete a set

ResponseResponse

• Muscle response is a function of time under tension ( tempo-rep, TUT-set)

• For size ( hypertrophy) TUT must be 30-70 sec

• For strength less than 1-20 sec.

Length TensionLength Tension

• Length tension relationship• There is an optimum length at which a muscle can produce it’s greatest force.

• A muscle must be lengthened to be able to shorten effectively

• Max force is at normal length• Hamstring example

VelocityVelocity

• Velocity is displacement/ time• Acceleration is change in velocity• Sport is about acceleration not velocity

• Sprints measure acceleration, not speed

• 4.5 forty? Is that velocity? 40 yds in 4.5 sec. Velocity is 8,8 yds/sec

• Displacement is 40 yds

• Displacement is 40 yds

Force Velocity CurveForce Velocity Curve• Muscle has an inherent capacity to adjust force to match load. This is what separates it from simple elastic contractions. ( Edman in Komi p 105)

• Max load= minimal velocity-- (strength)

• Minimal Load= high velocity- (power)

• Training must be at various loads and speeds

• Plyometrics are designed to use the stretch shortening cycle to effect the force velocity curve.

• In other words, they teach you to move heavier loads faster.
